To clean the 90° mirror, raise the splice top and flip the 90° end view mirror down. Wipe it with the cotton swab
and lens cleaner using a single-direction stroke.
Since it is harder to view, the 135° mirror must be cleaned with the aid of the image. Close the splice top to
display the image from the 135° on the computer screen. Raise the splice top and wipe the 135° mirror with a
single stroke. Close the top and reexamine the mirror surface in the image. Continue in this manner until the
mirror is sufficiently clean.

11.4.2. Check/Clean Graphite V-Grooves
The splice station uses graphite vacuum V-grooves to precisely hold the fiber for alignment and splicing. Any
small amount of dirt or debris that collects at the bottom of the V-groove could cause alignment and/or strength
issues.
A special long-hair, anti-static brush cam be used specifically for cleaning the graphite V-grooves. Gently brush
out any dirt or debris that is apparent in the V-grooves. If necessary, the V-grooves can be blown clean using
clean dry (canned) air.
Note: The graphite material is very soft to ensure that it will not scratch the glass fiber. It can easily be damaged
or scratched. Never use any metal or hard materials to clean the graphite V-grooves. Even the “soft” blue handled
brush has sufficiently hard bristles to damage the graphite. Use only canned air or a “long-hair” anti-static brush.
11.4.3. Replace Filament
1. Raise the splice top.
2. Loosen the 2-56 setscrews on the filament extraction tool using a 0.035" hex key.
3. Locate the slotted end of the extraction tool over the filament in the splice head with the setscrews facing
to the right. Make sure the extraction tool is centered front-to-back and is sitting flush on the splice head.
4. Tighten both setscrews on the extraction tool to clamp the filament.
5. Gently lift the filament straight out using a slight front-to-back rocking motion.
6. Remove the filament assembly from the extraction tool by loosening the setscrews.
